You are correct, the Towitoko/USB is using PL2303:
ucom0: Prolific Technology PL2303 Serial adapter (ATEN/IOGEAR UC232A), rev
1.10/2.02, addr 2
debugging the RS232, i see that it starts at 1200bps/7bits but switches to
9600 bps/ 8 bits very early on, i'll have to check the Towitoko driver to see
if it
can do without the initial 1200/7bits.
